EXTE NSION-TAB LE Specification of Letters Patent.

Patented Dec. 29, 1908.

Application filed September 27, 1907. Serial No. 394,791.

To all whom it may concern:

Be it known that I, RANDOLPH F.-WEsTE R- FIELD, a citizen of the UnitedStates, and a resident of New York city, in the county of New York andState of New York, have invented certain new and useful Improvements inExtension-Tables, of which the following is a specification.

The invention relates to improvements in extension tables; and itconsists in the novel features and combinations of parts hereinafterdescribed, and particularly pointed out in the claims.

The invention pertains more, especially to an extension table adapted toconceal within itself an extension leaf orextension leaves and providedwith suitable means for effecting, upon the table being extended, theelevation of said leaf or leaves to the horizontal plane of the tabletop and, upon the contraction of the table or the shoving together ofthe end sections thereof, causing said ex-' tension leaf or leaves todisappear below the table top. I

My invention while applicable to various constructions of extensiontables, relates more particularly to improvements on the \Uesterfieldand Randolph F.

extension table shown and described in Let-.

ters Patent of the United States N 0. 780,927 granted January 24, 1905to Eugene. T. Westerfield. The table shown in said Letters Patent isadapted upon being extended to expose and elevate the extension leavesand upon being contracted to depress and close in said leaves. When thetable of said patent is extended and the extra leaves elevated toposition, the objectionable condition exists of there being no sideframes along the ends of the extension leaves to with the side framesalong the sides of the main end sections of the table, and one of themain objects of the present invention is to remedy this objection andprovide an extension table in which the extension leaves are formed withhinged side frames adapted to be folded under when the extension leavesare concealed below the main table top and to be turned outwardly whenthe table is extended, to match the remaining edge and side portions ofthe table, whereby the table when completed possesses a finishedappearance and is uniform throughout the length of each side thereof.

My invention also comprises means connected and cooperating with thehinged side match or coincide The invention will be fully understoodfrom the detailed description hereinafter presented, reference being hadto the accompanying drawings, in which:

Figure l is a perspective view of a table constructed in accordance withand embodying the invention, the table being shown in its extendedcondition; Fig. 2 is a like view of the same, the table being shownartly extended; Fig. 3 is avertical central on itudinal section, partlybroken away, of t e table, the latter being shown in its contractedcondition with the extension leaves concealed below the table-top, andthe section being on the dotted line 33 of Fig. 4; Fig. 4 is a top view,partly broken away, of the table in its contracted condition; Fig. 5 isan enlarged central vertical longitudinal section through the u perportionof the table, the latter being i ustrated in a partly extendedcondition and the section being on the dotted line 55 of Fig. 6; Fig. 6is a top view, partly broken away, of the same Fig.

7 is a vertical transverse section through the upper portion of thetable on the dotted line 7-7 of Fig. 4 Fig. 8 is alike section throughthe upper portion of the table on the dotted lines 88 of Figs. 5 and 6;Fig. 9 is a detached pers ective View, artly broken away, of one of t eextension leaves; Fig. 10 is a detached perspective view, partly brokenaway, of a portion of the supporting frame and guide rails of the table,and Fig. 11 is a detached sectional view through a portion of one end ofthe table at the point where a latch is provided for securing the endsecltion of the table to one of the stationary ra1 s.

In the drawings, 20, 21 designate the main table top sections, 22, 23the sections of the main support for the table, and 24, 25, theextension leaves normally concealed below the end sections 20, 21, asshown in Fig. 3. In addition to the supports 22, 23, which are ofpedestal character, the table is provided with a middle supporting leg26, which, wlten the end sections are together, is concealed within achamber formed by the supports 22, 23, the latter matching each other inthe contracted condition of the table and presenting the appearance ofan integral pedestal support.

With reference to the general supporting frame of the table, atransverse bar 27 is secured upon the upper end of the middle leg 26,and upon the ends of the bar 27 are secured the longitudinal stationaryrails 28. Upon the upper portions of the pedestal sections 22, 23 aresecured the transverse bars 29, while upon the horizontal extensions 30attached to said sections are secured the transverse bars 31. The bars29, 31 extend entirely across the table and are secured to the sides 32of the end sections thereof, said end sections when separated from oneanother each carrying one of the pedestal sections, with the bars 29, 31connected therewith.

The bars 29, 31 of the right hand section 21 of the table, looking atFig. 6, have secured upon them the corres onding sliderails 33, and thebars 29, 31 of the left hand section of the table have secured upon themthe corresponding slide-bars 34. The

' bars 33, 34 are disposed at opposite sides of the longitudinal centerof the table and guide upon the sides of the stationary bars 28, asusual, tongues and grooves being provided in the adjoining faces of saidbars for guiding them. When the table is in a contracted condition (Fig.4) the left hand ends of the bars 33 of the table section 21 are abovethe transverse bars 29, 31 of the left hand end section 20, and theright hand ends of the bars 34 of the table-section 20 are above thetransverse bars 29, 31 of the right hand end section 21.

The features of the supporting frame hereinbefore designated and so faras they have been described, are of usual form and construction andrequire no special description.

My invention pertains to the extension leaves 24, 25 and the featuresconnected therewith and with the bars 33, 34 for effecting theirconvenient use and operation.

In the present instance I employ two extension leaves, numbered 24 and25 respectively, but the invention would be present if only one of saidextension leaves were made use of, and in actual practice only oneextension leaf is exposed for use, unless a table of extra length isrequired, under which condi tion both extension leaves will be exposed.

I secure upon the outer sides of the inner ends of the rails 34 cam bars35 having cam or inclined surfaces 36, 37, said surfaces being set onein advance and one at the side of the longitudinal plane of the other,as clearly illustrated in Figs. 4, 6 and 10; and upon the inner sides ofthe inner ends of the rails 33 I secure cam bars 38 corresponding withthe bars 35 and having inclined or cam surfaces 39, 40, one being inadvance and at one side of the longitudinal plane of the other. The cambars 35, 38 are all alike, but arranged in pairs and point inwardly ortoward the central transverse bar 27. The cam bars 35, 38 being securedto the rails 34, 33 of the main end table-sections move with said.sections, and they are utilized to cooperate with the extension leavesand for effecting the elevation of said leaves when the end sections areextended and the depression of said leaves when said end sections arepushed together in contracting the table.

One of the extension leaves is shown detached in Fig. 9, in which it maybe seen that the leaf has secured upon its lower side two parallel bars41 whose inner ends are inclined or rounded, as at 42, and whose outerends, at the inner sides thereof, carry cam-blocks 43, the inner ends ofwhich are also rounded or inclined correspondingly with the ends 42 ofthe bars 41. Both leaves 24, 25 are provided with the bars 41 and.blocks 43, the bars and blocks of the leaf 25 cooperating with the cambars 38 carried by the sliderails 33, and the bars and blocks of theleaf 24 cooperating with the cam bars 35 carried by the slide rails 34,as may be understood by reference to Figs. 4, 6, 9 and 10. 'lhe blocks43 of the leaf 24 are at the outer sides of the ends of the bars 41 forsaid leaf. '1 he leaves rest upon the rails 28, 33, 34 when the table isin its contracted condition, and when the end sections of the table aredrawn out, the rails 33, 34 carry the cam bars 35, 38 against the bars41 and blocks 43 of the extension-leaves and effect the elevation ofsaid leaves, the inclined surfaces 40 and 39 of bars 38 respectivelyengaging the bars 41 and. blocks 43 of the leaf 25, and the inclinedsurfaces 37, 36 of the bars 35 respectively engaging the bars 41 andblocks 43 of the leaf 24, and said inclined surfaces by riding belowsaid bars and blocks forcing the leaves to elevate to the plane of themain table top.

The inner or adjoining ends of the extension-leaves 24, 25 carryvertical hinged pins 44 which are loosely housed in vertical apertures45 for holding the leaves in a fixed, location with relation to eachother and with the stationary part of the table but allowing said leavesto be moved vertically upward by the cam bars 35, 38. 'lhe pins 44 andapertures 45, the latter being in the stationary rails 23 are disclosedin the aforesaid Letters Patent No. 780,927 and not separately claimedherein. In the present instance, however, the pins 44 are employed inconnection with cam-bars 41 and cam-blocks 43, the latter not beingshown in the aforesaid Letters Patent.

The extension-leaves 24, 25 are each formed at its ends with hingedsections 46 comprising members 47, 48 and adapted to be folded under thebody of the leaf, as shown in Fig. 7, and also to turn outwardly, asshown 1 in Figs. 8 and 9 for imparting a uniform appearance to thetable, the members 47 of the lunged sections matching, when S:1l(lsections are turned outwardly, the top of the table and the edge of theend sections 20, 21, as

lllf) 'llO shown inFigs. 1 and 2, and the members 48 of said hingedsections matching the sides 32 of the said end sections, whereby, whenthe table is extended, its edges and sides become uniform throughout, inwhich respect the present invention constitutes a marked improvementover the table shown and described in the aforesaid Letters Patent No.780,927. The adjoining edges of the extension-leaves and hinged sections46 are mitered, as shown in Fig. 7, so that when the leaves are to beconcealed the members 48 of said hinged sections may turn up under theends of the leaves and the members 47 thereof stand vertically and passabove the transverse bars 29, 31 of the table frame.

It is desirable that the hinged sections 46 of the extension-leavesshall be locked in their folded position when the table is contractedand automatically spring to their unfolded or operative position whenthe table is extended, and to. this end I provide the leaf 24 with bars49, 50 carrying blocks 51, 52, respectively, and hinged at theirouter-ends to the sections 46 of the said leaf, and equip the leaf 25with bars 53, 54 carrying blocks 55, 56, respectively, and hinged to thesections 46 of said leaf 25. The bars 53, 54 are at their inner endspivotally connected with a pivoted lever arm 57 to which a spring 58 isconnected and which spring normally exerts its force to push the bars53, 54 outwardly. When the leaf 25 has its hinged sections 46 foldedunder its end portions the bars 53, 54 are in their extreme innerposition and the blocks 55, 56 press against the inner facing edges ofthe inner rails 33, as shown in Fig. 4, said blocks operating asshoulders to resist the outward movement of the bars 53 54 under thestress of the s ring 58. When the end-section 21 of the ta 1c is pulledoutwardly to carry the cam surfaces 39, 40 of cam-bars 38 against thecams 42, 43 of the leaf 25, said cams 39, 40 by riding against the cams42, 43 will elevate the leaf 25 and raise the blocks 55, 56 above therails 33, the spring 58 the moment the blocks 55, 56 become releasedfrom the inner facing sides of the rails 33, forcing said blocks andbars 53, 54 out wardly and thereby automatically opening or unfoldingthe hinged sections 46 of the leaf 25 and causing the said blocks 55, 56to pass upon the tops of said rails 33 where said blocks will operate assupports for the leaf 25 and coperate with the bars 41, blocks 43 andcam-bars 38 in holding said leaf on a level with themain table top.\lVhen it is desired to contract the table and effect the lowering ofthe leaf 25 down upon the rails 28, 33, 34, the attendant after pullingoutwardly on the end of the table so as to secure freedom for the leaf25 will press downwardly and inwardly upon the hinged sections46 of saidleaf so as to turn said sections under the ends of the leaf and, throughthe bars 53, 54,

force the blocks 55, 56 inwardly toward each other and from over the topof the rails 33, under which condition the end section of the table willbe pushed inwardly and the leaf 25 will lower upon the supporting rails,the blocks 43 and bars .41 riding down the cam surfaces 39, 40 of thebars 38, and the blocks 55, 56 passing downwardly along the facing sidesof the rails 33, where they operate as with their blocks 55, 56, leverarm 57 and spring 58, enable the securing of the hinged sections 46 attheir inward position when the table is in contracted condition, theautomatic turning outwardly of said hinged sections 46 when the table isextended and the imparting of movement from one of the hinged sections46 to the other thereof when either is moved either inwardly oroutwardly. The blocks 55, 56 also operate, when the table is extended,as supports for the outer edge of the leaf 25.

The bars 49, 50 for the leaf 24 carry their blocks 51, 52 in positionfor cooperation with the outer rails 34, said blocks engaging the outersides of said rails 34 when the table is contracted, as shown in Fig. 4and permitting said blocks to rest upon said rails when the table isextended (Fig. 6) so that they may then operate as supports for theouter edge of the leaf 24. When the hinged. sections 46 of the leaf 25are folded inwardl they move the bars 53, 54 and blocks 55, 56 inwardlyso that the latter may pass inwardly from offtherails 33', but when thehinged sections 46 of the leaf 24 are folded inwardly they must move theblocks 51, 52 outwardly, so that said blocks may pass to the outer sidesof the rails 34, and therefore the bar 49 carrying the block 51 ishinged to the section 46 shown at the left hand side of Fig. 8 and theblock 52 is carried by the bar 50 hinged to the section 46 shown at theright hand side of Fig. 8, said bars 49, 50 lapping one upon the otherfrom the middle of the table outwardly so as to occupy as little room aspossible, as indicated in Figs. 4, 6 and8. The bars 49, 50 at about themiddle portion of the table are pivotally secured to a lever arm 59connected with a spring 60, whose normal tension is exerted to force thebars 49, 50 outwardly in a direction from each other, this resulting,when the table is extended, in the hinged sections 46 of the leaf 24being forced outwardly to the position illustrated in Fig. 8. When the.

hinged sections of the leaf 24 are thus forced outwardly by the spring60 the bars 49, 50 have their free end portions drawn inwardly, due tothe fact that said portions pass by the center of the table, and drawthe blocks 51, 52 inwardly to a suflicient extent for said blocks topass upon the rails 34 and act as supports. l/Vhen the hinged sectionsof the leaf 24 are pressed inwardly, the bars 49, 50 have their endsmoved outwardly in opposite directions and carry the blocks 51, 52 offthe rails 34, said blocks then engaging the outer sides of said rails 34and operating as stops to resist outward movement of the hinged sections46 of the leaf 24. When the table is extended the cam bars 35 engage thebars 41 and blocks 43 of the leaf 24 and elevating the same raise theblocks 51, 52 clear of the rails 34, this allowing the spring 60 todrive the bars 49, 50 ouwardly for the purpose of opening the hingedsections 46 of said leaf and carrying the blocks 51, 52, inwardly uponthe rails 34.

The operation of the table will be largely understood from the foregoingdescription. Figs. 3 and 4 show the table in its contracted condition,the extension-leaves 24, 25 being below the main table-top sections andhaving their pins 44 loosely within the apertures 45 of the stationaryrails 28. At this time the end sections 46 of the extensiondeaves are infolded position under the ends of the leaves and thus held by theengagement of the blocks 51, 52 of the leaf 24 with the outer faces ofthe rails 34 and the engagement of the blocks 55, 56 of the leaf 25 withthe facing sides of the rails 33; and the said leaves are supported bythe rails 28, 33, 34. When it is desired to extend the table the endsections 20, 21 will be pulled outwardly from each other, if both leaves24, 25 are to be eX- posed, being drawn outwardly to a distance greaterthan the width of said leaves 24, 25, so that the latter may haveabundant opportunity to become elevated, and will then be pushedinwardly against the outer edges of said leaves 24, 25. The outwardmovement of the end section 21 will, through the rails 33, cause the cambars 33 to be drawn against the bars 41 and blocks 43 of the leaf 25 andeffect the elevation of said leaf, the hinged sections 46 of said leafspringing outwardly as soon as the blocks 55, 56 carried by the leaf areraised to the level of the rails 33. The movement of the end section 20outwardly or toward the left (looking at Figs. 3, 4, 5 and 6) willresult in the rails 34 being drawn toward the left and carrying the cambars 35 secured to them against the bars 41 and blocks 43 of the leaf24, thereby elevating said leaf and causing it to carry the blocks 51,52 thereof to a plane at which they may spring inwardly upon the rails34 and the spring 60 be enabled to unfold or move outwardly the hingedsections 46 of said leaf 24.

i l l If it is only desired to extend the table to such length as one ofthe extension-leaves might furnish, one end section of the table will bepulled outwardly, while the other one is stationary, this resulting inonly one leaf being exposed. when the end section 21 of the table ispulled outwardly from the section 20 the rails 33 will elevate the leaf25, and when the section 21 is allowed to remain at rest and the section20 pulled outwardly, the rails 34 will elevate the leaf 24.

It is customary in the employment of extension tables to provide meansfor latching the end sections of the table to the stationary middlerails 28, and in Figs. 4 and 11 l indicate diagrammatically a latch '70at each end of the table for securing the end sections to the rails 28,as usual. When. it is desired to extend the section 21 and not thesection 20,

the latch securing the section 21 to the rail 28 will be released sothat said section 2]. may be drawn outwardly. Should it be desired toextend both sections of the table, both of the latches would bereleased, and the latch 7 O for the end section 20 of the table would bereleased when it is desired to extend that section only.

The leaves of the table are provided with dowel pins, as usual, at theiredges, and liliewise the hinged sections 46 are provided with dowel pins(Fig. 9) for rendering them rigid when in use. When the table isextended the end-sections are drawn outwardly considerably beyond theleaves 24, 25 so that the latter may be elevated and the blocks 51, 52,55, 56 spring to position upon the adjacent rails, and thereupon theend-sections are Jushed together, the dowel pins and their sockets thenengaging each other and the extension leaves being supported by the bars41, cam blocks 35, 3S and blocks 51,52,
